A flex league is a recreational league for players of all levels and it allows players to schedule matches on their own time and convenience. Players are grouped by skill level into flights. Players are responsible for arranging matches via the app with other players in their flight, and matches can be played at any mutually agreed upon location and time. Flex leagues are a great way for players to compete against others at a similar skill level, improve their game, and meet new tennis partners.

Every league has multiple rounds in a year, which typically run for 8-10 weeks. The dates for each round can be found in the USTA Flex app. Your matches (typically between 5-8) must be played within the round dates.

If you already have a USTA account, all you need to do is download the USTA Flex app and log in using your existing USTA account credentials. If you don't have a USTA account, you will need to register (it’s free) for one in order to use the app.

To register for a USTA account, simply download the USTA Flex app and follow the prompts to create an account. Once you have a USTA account, you can log in and start playing.

Once you're logged in to the app, you can start browsing for flex leagues in your area. The app will also give you suggestions for leagues nearby. Follow the prompts to join a league, and you'll be ready to start playing matches against other players of your level as soon as a next round starts.

If you join a doubles league, your partner needs to have an account as well. Once you join the league, you can add them to your team.

For new players, flight placings are done based on their level as determined by the World Tennis Number (WTN) rating system. They will be placed into a flight with other players who have a similar rating.

For returning players, flight placings are determined based on a combination of level and previous results. The app will take into account a player's WTN rating, as well as their results from previous rounds. This means that players who perform well in previous rounds may be placed into a higher flight, even if their WTN rating hasn't changed significantly.

Overall, the goal of flight placings is to create competitive and balanced matches for all players, regardless of their level or experience. By grouping players with similar skill levels and taking into account their past performance, the app aims to provide a fun and challenging playing experience for everyone involved.

WTN, or World Tennis Number, is a real-time skill level rating system for tennis players that is powered by the International Tennis Federation (ITF). It calculates a player's skill level based on match results, opponent strength, and set scores. WTN ensures fair and competitive matchups by providing accurate ratings that reflect a player's current ability. It allows players to find opponents within their skill range and enjoy balanced gameplay. You can read more about WTN at https://worldtennisnumber.com/
